MV Mobeus weights 2.1kg is is far too heavy for a sub-notebook. I cannot find spec for Acer model you mentioned Acer website.
For reasonable price one, look Dell X300 (??) only 1.3Kg also 12" screen, dell site down, cannot find the price for you yet.
Samsuang, Panasonic (14" screen only 1.29kg), Sony produce better and lighter models, but more expensive.
For Christmas wishing list, have a look click here
